C4 Pre Workout Review (Original) – Why is it The Number 1 Selling Pre-Workout in the United States?

C4 is the pre-workout made by Cellucor, which has been around for quite some time now. Known mainly for their pre-workout which can be found in most retail stores, they do make other supplements as well but C4 is literally everywhere.


  • Best Place to Buy: Amazon.com
  • Size of Container: 195g (6.9oz) or 390g (13.8oz)
  • Serving Per Container: 30 or 60 servings
  • My Rating:7/10

I normally see them sold in my local Walmart store as well, Just the other day I was in Costco and I saw that they had a double pack with a shaker bottle for some ridiculously low price.

But does it really work? Whenever we take a pre-workout we are looking for that pump, and extra energy boost to make our workout easier. C4 is one of the most commonly used pre-workouts available on the market. Sometimes known as the best selling pre-workout, so what is making C4 sell so well?

Is it the fact that it works really well and people just love it? Or is it the fact that it is easily available at your local Walmart and you didn’t need to go to an actual vitamin or supplement store to get it. Let’s dive in and take a look at what is in C4.

C4 Ingredients

Other than a handful or so of vitamins this list of ingredients is relatively short, especially since we just got done reviewing that monster of a list that Pre JYM has in their pre-workout. So let’s dive in: C4 Original Supplement Facts

  • CarnoSyn Beta-Alanine 1.6g – CarnoSyn’s patented beta-alanine is a popular ingredient in sports nutrition today and you will find this ingredient in many pre-workouts. This popular beta-alanine is said to be the best quality beta-alanine you can find out there in the market. This is a great ingredient for a pre-workout as this ingredient is known to be able to help you sustain your workout for extended periods of time so you can workout longer and harder.
  • Creatine Nitrate (NO3-T) 1gCreatine Nitrate is essentially a more water-soluble version of creatine. It is creatine bonded to a nitrogen base. The idea is that the nitrate helps increase the oxygen levels in the bloodstream, which would in turn help with your strength during weight lifting. Though studies have been very limited so at this moment we can only expect it to be just as good as creatine monohydrate, but dissolve better.
  • Arginine Alpha-Ketoglutarate – This is a non-essential amino acid that helps with your workout performance, and recovery. It is supposed to help by boosting nitric oxide production helping you feel stronger and more pumped. Studies have been conflicting on this so we do not know if it is truly effective.
  • Explosive Energy Blend – This blend contains N-Acetyl-L-Tyrosine, Caffeine Anhydrous (150mg), Velvet Bean seed extract and Theacrine. I do not like anything that has proprietary blends, its just a way for manufacturers to hide how much of the ingredients they put in their products. N-Acetyl-L-Tyrosine has the potential to improve focus and Theacrine acts basically a stimulant like caffeine.

The Taste

For this review, I tried the Icy Blue Razz and I thought the flavor tasted pretty good. It was fairly sweet, it reminded me of how knockoff kool-aid taste. C4 is offered in a variety of different flavors, from all the people that I have talked to about C4, I have gotten good feedback from the other flavors as well. C4 comes in the following flavors:

  • Fruit Punch
  • Icy Blue Razz
  • Orange Burst
  • Pink Lemonade
  • Strawberry Margarita
  • Watermelon
  • Cherry Limeade
  • Orange Burst
  • Green Apple
  • Juicy Candy Burst
  • Frozen Bomsicle (NEW)

C4 uses sucralose as its sweetener, which is an artificial sweetener that is known by the trade name Splenda. It is said to be 320 to 1000 times sweeter than standard sucrose, which is regular sugar. Artificial sugar is known to potientially cause diarreah, bloating, gas, or be laxative to certain people. There shouldn’t be enough to cause these issues but keep an eye out for any reactions from your body.

There was also no residual powder left at the bottom of the shaker, which is common is a lot of pre workout supplements. C4 did a good job disolving so it didn’t feel as if you were drinking sand at the end of your pre workout.

The First Feels

The beta-alanine definitely does its job by giving you those first pins and needles tingly feeling on your skin. C4 has a relatively low caffeinine dose compared to many other pre workouts on the market. 150mg of caffeine is a decent amount but is just roughly 1.5 to 2 cups worth of caffeine, or about as much as a can of Monster energy drink.

Nevertheless, the 150mg of caffeine did do its job and wake me up a bit. I do have a fairly high tolerance when it comes to caffeinine so the most it did was just wake me up a bit, nothing too crazy.

The Workout

After about 45 mintues after taking the C4, I started my workout. The main ingredient is the beta-alanine which I am not a huge fan of due to the tingly sensation that it leaves you.  At first, I didn’t notice too much pump, but after a couple sets into my workout, I started to notice that my sets were getting a bit easier to do.

In the middle of my workout, I was able to feel a decent rush, a bit of focus and some pump. It helped me grind through the rest of my workout with relative ease.

Remember just as with any pre workout, effectiveness will vary from person to person. The amount of time it took for me to feel my pump might not be exactly the same as yours.

The Crash

As with most pre-workouts, most people are worried about a horrible crash after their workout. C4 didn’t provide me with an extreme crash after my workout. I felt the effects of C4 slowly fade away without making me feel an extra tired. The caffeine content in this pre workout isn’t extremely high when compared to other pre workouts on the market such as Legion’s Pulse as well as Pre Jym which both have 300mg + of caffeine. Which in turn made it a lot easier for me to sleep later on at night time.

The Verdict Is…

I enjoyed C4, for as inexpensive as it is and widely available it works fairly well. It is easy to see why it is the number 1 selling pre workout. Aside from it being available in many local retailers, it does what it says at giving you that extra pump you need to get through your workout.

The blend of ingredients gives you a nice boost of energy, without giving you a noticeable crash. C4 does have artificial ingredients so if you are ok with that then C4 is a great choice.
